The wingspan is about 11 mm. The forewings are black, partially dark grey and the dorsum with a rather broad, very pale ferruginous-white streak from the base to the tornus, slightly attenuated towards the extremities and with a small white tooth on the upper edge along the fold. There is a rather broad and straight, oblique white transverse fascia with parallel and well-defined edges. The lower third of this fascia is extended as a horizontal band posteriorly. About the apical sixth of the wing is white, containing a suffused grey-black rounded blotch, filling out the apex and connected with the ground color in the disc below the middle of the wing. The hindwings are light greyish fuscous.[3]
